ABSTRACT
To better support these activities and collaborations, information technology (IT) infrastructure and systems are needed that are more convenient to use. We expect, for example, that personal preferences and proŸles of individuals will be readily available when shopping over the Internet or when running jobs on a computing grid, without requiring the individuals to repeatedly enter them. In such a scenario, digital identity management (IdM) technology is fundamental in customizing user experience, underpinning accountability in transactions, and complying with regulatory controls. For this technology to fully deploy its potential, it is crucial that strong protection of digital identity be achieved. IdM systems must assure that such information is not misused and individuals’ privacy is guaranteed.
